growth. Spirals — the earlier whorls are keeled by three equal, 

 equally prominent, and equally parted rounded threads ; on the 

 last whorl others, weaker, appear between these ; the lowest of 

 the three loses in importance, and about seven others, not all quite 

 equal nor quite equally parted, occupy the base, while four or five 

 more somewhat similar cover the snout. Colour probably white, 

 but stained with mud in which the specimens have lain. Apex : 

 there are 4 embryonic whorls, which form a high cone with a 

 slightly impressed suture; the extreme tip has evidently been 

 small, but is broken : the sculpture is not typical, but consists of 

 a series of straight bars ornamented with rough and projecting 

 tubercles ; these cross the whorls, but at the top and bottom of 

 the whorls another set of short little bars occur between the 

 larger ones. Whorls : these are 9 in all, of regular increase, 

 rather short ; above they are slightly concavely horizontal, at the 

 three keels cylindrical, and below this contracted into the infe- 

 rior suture ; the last whorl is very short, a very little swoin, 

 with a very short rounded base and a small snout. Suture 

 impressed, but open. Mouth small, oval, rounded above, and 

 drawn out into a canal below. Outer lip straight in the sinus- 

 area, high-arched in the middle, concave in front, and straight 

 along the canal : the edge forms a high shoulder above, between 

 which and the body is the open, deep, rounded sinus. Inner lip 

 thinly excavated, very early cut off at the sharp oblique edge of 

 the pillar. H. 023. B. 009. Penultimate whorl, height 0-045. 

 Mouth, height 0'09, breadth 0'05. 



This species is classed under Defrancia only provisionally with 

 a mark of interrogation, in consequence of the departure of the 

 embryonic whorls from the typical sculpture. That sculpture 

 and form of apex may probably serve as the safest basis of classi- 

 fication in the whole group.

Shell. — High, narrow, fusiform, white, with pale irregular 

 ruddy-brown spots near the suture and at the apex, which is 

 small and sharp ; the whorls are rounded and reticulately 

 ribbed, the last narrow and drawn out on the base ; it has a high 

 subscalar spire ; the mouth is long and rather narrow, the outer 

 lip thickened within and without, with a small sinus above and a
